CC='gcc -arch i386' ./configure --with-ns --without-x
make bootstrap

Turns out that I had a /usr/local/include/mach-o directory with the  
old loader.h file.
It looks like it was installed along with llvm in spring 2008.  It may  
have been part of a free iPhone OS related build stack that I  
installed around that time.

I've fixed it for myself, but I can't tell how likely this sort of  
thing will happen on other people's systems.  It's of course a problem  
with whatever I installed back then rather than with your code.

That brings up charset.o, lread.o and term.o.

Well, I did a "make clean" and started from scratch with the 10.4  
deployment target, and the results run fine on 10.5.
